SKYLIGHT QR VENTILATED ROOF.

Application filed August 23, 1920. Serial No. 405,306.

T all wit-Om it may concern. i Beit known that I, SAMUEL J. OLsHiN, acitizen of the United States residing at 1 Underclifi', Yonkers, in thecounty of Vestchester and Sta teof New York, have invented certain newand useful Improvements in Skylights or Ventilated Roots, of which thefollowing is a specification.

This invention relates to'an automatically operated ventilator, One ofthe objects of the invention is topro videa ventilator that will openautomaticallyin case of fire- Another object is to provide a ventilatorthat may be opened and closed manually'with a minimum of noise. Anotherobject is to pro-vide a ventilator that is substantially air tight whenin a closed position. Another object is to provide a ventilator thatwill not let rain into the building even when the ventilator is in itsopen position unlessthe rain is accompanied by a' considerable amount,of wind. Another object is to provide a ventilator that will in itsclosed position efi'ectively shutout rain even in the 2 most violentstorm. "Another object is to provide a. ventilator byrneans of whichadequate ventilation can be secured in a practical and convenient-1nanner. Other objects and advantages of the invention will be ob- 0vious asthe description proceeds.

The invention will be understood from the following description and theaccompanying drawings. which show an embodiment of j the invention inwhich the same reference characters refer to the sameparts in thedifferent views. I p

Inthe drawings: v p I I Fig. 1 is a side view of-the device as used 7 onthe side of a peak roof; I s 4 Fig. 2 is a similar-view showing thesashes in a closed position on the other side of the peak roof; 7

'Fig. 3 is a plan view; Fig. is a perspective view showing a sashandoperating rods;

Figs. 5 and 6 are views showing details of the mechanism. s I I In thedrawings reference character refers to. the rafters which are showncoming together at the .top in 'a peak roof skylight. Pivoted betweenthe rafters 1 are series of window sashes 2, 2, 2, etc., so mounted thatthe'lower edge o-feach sash overlapsthe upper edge of the one below itwhen the sashes are in a closed position as shown in F The sashes areeach provided with a pro ectmg hp 3 extending along the under slde oftheir loweredges andwith a strip 4 of resilient material such as rubberfor ex ample extending alongthe top'sideof'the upper edge thereof. Thestrips 4 may be provldedwith notches 5 so as to fit more closely theframework'or outlines along the underside of the sashes above, withwhich they come into contact when they are in a closed position, therebyforming substantially air tight joints between contiguous sashes. i

v Extending from each side of the sashes 2, 2.,'etc. near the point 6(Fig. l) at which the sashes are pivotedyare brackets 7 that areconnected by pivots 8 to operating bars there being an operating bar 9along 'e'ach side of every series or setof vertical sashes.

Each operating bar 9 is pivotally connected by a link 10that is alsopivotally connected to an arm 11 which arin llis in turn rigidlyconnected to. the operating rod or shaft 12 whichis mounted to turn inbearings 13 mounted upon cross pieces 14: which are secured to therafters 1 at a convenient height. The arm 15 is adjustably connected bymeans of a set screw '16'to the rod 12in such ajposition that the'arm15comes into Contact with and isstopped in its travel by'the oper'atingsha ft or rod 12 for the sashes on the opposite side of the peak rootskylight which is show iniFig. 2. .The operating rod 12' for its; sideoffthe skylight shown in its actuallposition in dotted lines in Fig.1,the views inthe two figures showing thetwo respective sides. of theskylight slightly separated from each other, and the sashes being shownopen in one view and closed in the other view. It is obvious that byadjusting the position of the, arm 15 on rod 12 by means'ot-set screw16* the extent to which the sashes can be opened will be determined.

The end of the arm 15 and theend of a corresponding arm on the rod 12will be connected to thebifurcated end of a rope 17 which has a fusiblelink 18 therein.

i 'ltis impractical to mount the sashes 2 between Ith'efraft'ers 1 witha sufficiently close fitto prevent water from entering between the sidesofthe sashes and the sides of the rafters. In fact since it is desirableto have the sashesQ to turnfreadily on the r p vots it is advisable tohave a small, free space between the two. This makes it necessary toprovide a cover arrangement for these spaces between the rafters and theadjacent sides of the sashes. Such an arrangement is shown consisting ofcovers and 21 correspond ing to or suitable for each pair of side-bysidesashes. substantially the same shape in cross sect-ion which shape isclearly shown in Fig. 5. The cover 20 is pivoted at the points 22 to therafter 1 and its lower end extends a short distance below the point 6where the corresponding sash is pivoted to the rafter 1. The cover 21 isof substantially the same Shape as the cover 20 and is fixedly connectedto the adjacent edges of side-by-side sashes'in such a manner as toextend horizontally over the spaces between the sashes 2 and rafters 1,thereby forming a continuous sash. The upper end of the cover 21terminates somewhat below the pivot points 6 so as not to interfere withthe opening of the sashes. The cover 20 which is pivoted to the rafter 1overlaps the upper end of the cover 21 and the cover 21 overlaps theupper end of the next lower pivoted cover 20. The cover 20 may be offsetnear its upper end as shown at 23 in order to facilitatethisoverlapping." M v j The ,operationis as follows: VVhenit is desired toclose the ventilator, tension is applied to the rope 17 whereupon thearms 15 are pulled downwardly and the operating rods 12 and 12 areturned in their bearings thus through the mediation of the arms 11,links 10, and operating bars 9 the sashes are all turned together abouttheir pivot points 6 to their closed position as shown in Fig. 2. Theresilient strips. a of the respective sashes come into contact withthelower sides of adjacent sashes that are higher up thus providing asubstantially air tight ven tilator. ,When the rope 17 is released orwhen in caseof fire the fusible link 18 is melted the weight of the rods,9 etc. will turn the sashes to their openposition as shown in Fig. 1.If necessary the sashes may be so pivoted as to tend normally to turn totheir open position by having the pivot points nearer their lower thantheir upper ends. By proper adjustment of the arm 15 on the rod 12.,thesashes can be made to stop at the desired open position with the arm 15in contact with the lower side of rod 12. Preferably, this adjustmentwill be so made that when the sashes are in their extreme open positionthey will slope downwardly slightly thus takingcare of ordinary rainthat does not-descend at too great a slant. When the sashes are beingturned about their pivots 6 towards their open position the covers 21are carried upwardly and the covers 20 are turned about their pivots 22,their lower ends sliding along the These covers 20 and 21 are of tops ofthe covers 21 to the positions shown in Fig. 1.

lVhile the invention has been described as applied to a peak roofventilator it is obvious that it is also applicable to a ventilator thathas only one sloping side. It is also obvious that since the usualbuilding regulations permit the total area of glass to be as small asthe area of the opening through the roof, a portion of the glass can beleft off and sheet iron or other material substituted therefor. Thismodification does not violate the requirement that the total ventilateing space when the sashes are open shall equal the opening throughthe.roof.

In a device of the class described, a pivoted window sashand means for auto,- matically turning said sash to a predeterminedposition, said means comprising a rotatable rod and an adjustable arm onsaid rod.- I 2.
